An emoticon used to alter the emotional content of a message so that it appears to have a different meaning than the sender's actual intentions.

Often, a decepticon is used to "soften the blow" of bad news or to veil a threat.

At the climax of sexual intercourse pretend that you're going to aim for the mouth when depositing your load, but instead hit em in the eye and say "more than meets the eye." Then proceed to "roll out!" As an option, you can choose to wear a transformer mask w/ voice changer.
My ex-girlfriend is pissed that I gave her a decepticon. Now she has a lazy eye. I had to roll out fast.
